Digital Camera AA battery

2,181 52 June 1, 2018 at 08:12 PM
I was taking a video on a canon digital camera - the battery low sign came up and it closed the app/shuts off the camera. (non rechargeable).

I then used re-chargeable battery which is typically lower voltage, say around 1.33V - it lasted the entire event.

Now I measured the non rechargeable Duracell battery - it gives me 1.44V - is it still good? Then why it would not power the Video camera function?

a tester that puts a small load on the battery can be more useful than simply measuring the voltage.

Rechargeable (NiMH) batteries, even though they have lower nominal voltage, last longer in high drain devices because the voltage don't drop much under load, compared to the alkaline batteries. Even though alkaline batteries have higher initial nominal voltage, once under load, the voltage drops much lower. So, even though you're seeing 1.44v out of the camera, it is too low to power the camera.

Disadvantage to the NiMH batteries is that they self-discharge much faster. What you want is the Low Self-Discharge (LSD) batteries with high capacity.

Panasonic Enloops are commonly recommended but even the Amazon basics or Ikea Rechargeables are quite good. https://www.ikea.com/us/en/catalo.../70303876/ All 3 I mentioned here are LSD.

That said digital cameras made in the last 5+ years typically use rechargeable lithium ion batteries because of their higher voltage and much greater energy density per gram, and per volume.

Image sensors improve at a slower rate than CPUs, but newer image sensors are generally a big improvement too. Especially the BSI CMOS type sensors compared to older senors.
